Abstract
A saw blade for medical, in particular surgical, applications having a recess for mounting the saw blade inside a saw which exerts an saw movement, especially an oscillating saw movement, to the saw blade. In order to improve the dynamic behavior of the saw blade, longitudinal flat areas of a surface of the saw blade are provided with a plurality of superficial impressions of a defined contour that are aligned at an angle to the longitudinal axis of the saw blade.
